GROSS ANATOMY

Detailed explanation-1: -The bony pelvis can be divided and viewed into 2 parts: anterior and posterior. The anterior part is called the pelvic girdle which is composed of the pubis, the ischium, and the ilium. It is connected posteriorly to the pelvic spine. The pelvic spine consists of the coccyx and sacrum.

Detailed explanation-2: -There are three bones of the pelvis: the hip bone, sacrum and coccyx. These bones connect the axial skeleton to the lower limbs, and therefore play a role in bearing the weight of the upper body. These bones also act as attachments for many muscles and ligaments within the pelvis and lower limbs.

Detailed explanation-3: -Although pelvises can be classified according to diameter, in obstetric practice they are often divided into 4 main types: gynecoid, android, anthropoid, and platypelloid, based mainly on the shape of the pelvic inlet [5].

Detailed explanation-4: -The pubic symphysis is a cartilaginous joint located between the main body of the pubic bone in the midline. The symphysis of the pubic bone is covered with hyaline cartilage and may have a cleft. The ligaments around the pubic symphysis are flexible and relax during pregnancy.

Detailed explanation-5: -Ilium. The broad, flaring portion of the hip bone (the crest of the pelvis). Pubis. The lower, posterior part of the hip bone. Ischium. One of the bones that helps form the hip.
